in reply to pass subroutine value to scalar

The subroutine as your have coded it doesn't actually have a meaningful return value. The problem is that the "system" command does not capure the output text of the command. Perl has a different operator for that:
sub ctrl { return qx/xmmsctrl print %T/; } my $ctrl = ctrl();
The qx operation could also be written using backticks:
sub ctrl { return `xmmsctrl print %T`; }
--Dave
Opinions my own; statements of fact may be in error.

[stevieb]: interestingly enough, someone else got my Devel::Examine:: Subs distribution for their PRC, and I applaud the change. This dist is extremely complicated and mostly obfu, but the person doing it understood PPI enough to change...
[stevieb]: ...something I had overlooked in the extreme depths of the core functionality. After merging, then a couple of extra tweaks, I still have 100% test coverage. Yay for people who write tests!
